Wow those are some beautiful Angels, and they are paired?
CVR has a PAR meter that they pass around, you just have to be a contributing member and be on the waiting list. I am not sure if you are a CVR member but if you were interested in it I could vouch for you if you are a new member, and I am sure there are others as well.
Funny, I get a lot of great close up shots of my tank, but never seem to get any good full tank shots, I think it requires a much different focus from the shooter and a lot of shots that you can go through to find the perfect one. Most of the time my FTSs aren't even straight.
